What are the essential features of a spinal paralysis ? 



As a rule, both, sides of tlie body are involved (paraplegia). 

 Keflex movements may be absent, excessive or normal. 

 Atrophy of the affected muscles may be wanting or highly 

 developed (depends upon the seat of the active cause ; for this 

 reason the reaction of degeneration may or may not be 

 present). 



Which are the peculiarities of peripheral paralysis f 



As a rule, certain groups are involved (monoplegia). Ee- 

 flex movements soon cease to exist, degenerative atrophy of 

 the paralyzed muscles is common ; the reaction of degenera- 

 tion is present. 



What points do you consider in establishing the seat and 

 cause of a paralysis 9 

 The development, course and extent of a paralysis. 



What deductions can you mahefrom the development of a 

 paralysis ? 



When developing suddenly it suggests a traumatism, 

 while slow development indicates a tumor or strangulation of 

 the nerve by scar tissue. 



Which peripheral paralyses are of special surgical interest ? 



1. Suprascapular nerve paralysis. 2. Radial paralysis. 

 3. Crural paralysis. 4. Facial paralysis. 5. Paralysis of the 

 motor branch of the trigeminal nerve. 



W hich are the peculiarities of suprascapular nerve paralysis ? 



At the moment the leg supports weight the scapula is 



•suddenly jerked • away from the thorax. Later follows 



atrophy of the antea and postea spinatus and teres major. 



The prognosis is unfavorable, as most cases do not recover.
